gdb: make some variables static

I'm trying to enable clang's -Wmissing-variable-declarations warning.
This patch fixes all the obvious spots where we can simply add "static"
(at least, found when building on x86-64 Linux).

gdb/ChangeLog:

	* aarch64-linux-tdep.c (aarch64_linux_record_tdep): Make static.
	* aarch64-tdep.c (tdesc_aarch64_list, aarch64_prologue_unwind,
	aarch64_stub_unwind, aarch64_normal_base, ): Make static.
